I run out of ideas. If you can not get your CPU to step speeds automatically, that's really bad. So you can not load acpi-cpufreq, but what about speedstep-centrino? It works a bit different and does not need ACPI that much. If you can make that work I think that would at least help a bit, and somew...

Heya. Yes, our Howto's are a bit out of date. Basically you need three things on ubuntu: - a Kernel where acpi-cpufreq is not build in but available as module - our patch - build tools (compiler, make, etc) - you can use the meta-package build-essentials Unfortunately Ubuntu decided to compile the c...

It does load clockmod-p4 there, too? Then I think you have a broken BIOS. How ever, can you unload the clockmod-p4 and force acpi-cpufreq to load, then? Are there some options in the BIOS where you can set up something that the hardware or the software takes care of CPU speed? I think I remember see...

Hello, what package are you using? In the download section there is a new package with ending -11 . It contains patches for .33 and .34 and a modified Makefile that should prevent the problem you've described. Please report back if you just have used the "wrong" package or if there is still a proble...

Sorry for the late answer. The message "unknown symbol..." normally appears if the kernel module somehow does not match the kernel. I can not say for sure if an I-series CPU does work with PHC yet. We do not have enough data about that but it would be interesting. The error you got is at least not c...

p4-clockmod is not suitable for a Core CPU (it is designed for a Pentium 4). As you tried to load the acpi-cpufreq module, did you unload any other cpufreq driver first? The message "no such device" makes me wonder. If the CPU is blocked already by another driver the error message would normally be ...

For sure its a software problem. That tool does basically the same as PHC does. The difference that PHC alters the ACPI table so the CPU will get your own VIDs each time it switches frequencies. Using c2ctl ( at least I think ) you need to set the VIDs manually. How ever. Can you tell us what happen...

What Distribution are you running? What makes me wonder is the fact that you use speedstep-centrino. This driver is deprecated for a while and has been reduced in functionality. You should try to use acpi-cpufreq as CPU frequency driver (normally shipped with every distribution). That driver should ...
